Kalanchoe plant named &#39;dokalnol&#39;

ABSTRACT

A new and distinct cultivar of  Kalanchoe  plant named ‘Dokalnol’, characterized by its compact, upright and uniformly mounded plant habit; moderately vigorous growth habit; freely branching plant habit; glossy dark green-colored leaves; uniform, early and freely flowering habit; large double bright yellow orange-colored flowers; and excellent postproduction longevity.

Botanical designation: Kalanchoe blossfeldiana.

Cultivar denomination: ‘DOKALNOL’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Kalanchoe plant,botanically known as Kalanchoe blossfeldiana and hereinafter referred toby the name ‘Dokalnol’.

The new Kalanchoe is a product of a planned breeding program conductedby the Inventor in De Lier, The Netherlands. The objective of thebreeding program is to create new freely-branching and freely-floweringKalanchoe plants with attractive leaf and flower coloration.

The new Kalanchoe plant originated from a cross-pollination made by theInventor in De Lier, The Netherlands in April, 2011 of a proprietaryselection of Kalanchoe blossfeldiana identified as code number 5545-01,not patented, as the female, or seed, parent with a proprietaryselection of Kalanchoe blossfeldiana identified as code number 6188-03,not patented, as the male, or pollen, parent. The new Kalanchoe plantwas discovered and selected by the Inventor as a single flowering plantfrom within the progeny of the stated cross-pollination in a controlledenvironment in De Lier, The Netherlands in May, 2012.

Asexual reproduction of the new Kalanchoe plant by vegetative terminalcuttings in a controlled environment in De Lier, The Netherlands since2012 has shown that the unique features of this new Kalanchoe plant arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Kalanchoe have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature, daylength and light intensity without, however, anyvariance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Dokalnol’. These characteristics incombination distinguish ‘Dokalnol’ as a new and distinct Kalanchoeplant:

-   -   1. Compact, upright and uniformly mounded plant habit.    -   2. Moderately vigorous growth habit.    -   3. Freely branching plant habit.    -   4. Glossy dark green-colored leaves.    -   5. Uniform, early and freely flowering habit.    -   6. Large double bright yellow orange-colored flowers.    -   7. Excellent postproduction longevity.

Plants of the new Kalanchoe can be compared to plants of the femaleparent selection. Plants of the new Kalanchoe differ from plants of thefemale parent selection in the following characteristics:

-   -   1. Plants of the new Kalanchoe are more freely branching than        plants of the female parent selection.    -   2. Plants of the new Kalanchoe have smaller leaves than plants        of the female parent selection.    -   3. Plants of the new Kalanchoe flower earlier than plants of the        female parent selection.    -   4. Plants of the new Kalanchoe and the female parent selection        differ in flower color as plants of the female parent selection        have dull yellow orange-colored flowers.

Plants of the new Kalanchoe can be compared to plants of the male parentselection. Plants of the new Kalanchoe differ from plants of the maleparent selection in the following characteristics:

-   -   1. Plants of the new Kalanchoe are more compact than plants of        the male parent selection.    -   2. Plants of the new Kalanchoe are more freely branching than        plants of the male parent selection.    -   3. Plants of the new Kalanchoe have larger flowers than plants        of the male parent selection.    -   4. Plants of the new Kalanchoe and the male parent selection        differ in flower color as flowers of plants of the male parent        selection are dull yellow in color.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoeblossfeldiana ‘Brazil’, not patented. In side-by-side comparisons,plants of the new Kalanchoe differ primarily from plants of ‘Brazil’ inthe following characteristics:

-   -   1. Plants of the new Kalanchoe are more freely branching than        plants of ‘Brazil’.    -   2. Plants of the new Kalanchoe have larger flowers than plants        of ‘Brazil’.    -   3. Plants of the new Kalanchoe flower earlier than plants of        ‘Brazil’.    -   4. Plants of the new Kalanchoe and ‘Brazil’ differ in flower        color as flowers of plants of ‘Brazil’ are light yellow orange        in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearanceof the new Kalanchoe plant showing the colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the photographs may differ slightly from the color valuescited in the detailed botanical description which accurately describethe colors of the new Kalanchoe plant.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurementsand values describe plants grown during the autumn in 10-cm containersin a glass-covered greenhouse in De Lier, The Netherlands and undercultural practices typical of commercial Kalanchoe production. Duringthe production of the plants, day temperatures ranged from 20° C. to 22°C., night temperatures ranged from 19° C. to 21° C. and light levelsranged from 10,000 lux to 55,000 lux. Plants received long day/shortnight conditions (more than 14 hours of light) for three weeks thenplants received photoinductive short day/long night conditions (minimum14 hours darkness) until flowering. Plants were 16 weeks old when thephotographs were taken and 17 weeks old when the description was taken.In the detailed description, color references are made to The RoyalHorticultural Society Colour Chart, 2007 Edition, except where generalterms of ordinary dictionary significance are used.
